Setting Up Replication When Data Volumes are Empty
Since the Primary data volumes are empty, there is no need to initialize the data on the
Secondary node.
On the Secondary: v240
1. Make the data volumes. Use different disks for the data volumes and SRL.
# vxassist -g hrdg make hr_dv01 100M \
layout=mirror logtype=dcm mirror=2
# vxassist -g hrdg make hr_dv02 100M \
layout=mirror logtype=dcm mirror=2
2. Make the SRL on disks other than the ones used for the data volumes.
# vxassist -g hrdg make hr_srl 50M mirror=2
3. Make the RLINK.
# vxmake -g hrdg rlink hr_v241_rlk remote_host=v241 \
remote_dg=hrdg comment=”secondary for HR at v241” \
remote_rlink=hr_v240_rlk local_host=v240 \
synchronous=off srlprot=dcm
4. Make an RVG, and associate the RLINK, data volumes, and SRL with the RVG.
# vxmake -g hrdg rvg hr_rvg rlink=hr_v241_rlk \
datavol=hr_dv01,hr_dv02 srl=hr_srl primary=false \
comment=”secondary for HR at v241”
5. Attach the RLINK to the RVG.
# vxrlink -g hrdg att hr_v241_rlk
6. Start the RVG to enable reads on the underlying data volumes (Secondary data
volumes are read-only).
# vxrvg -g hrdg start hr_rvg
On the Primary: v241
1. Make the data volumes. Use different disks for the data volumes and SRL.
# vxassist -g hrdg make hr_dv01 100M \
layout=mirror logtype=dcm mirror=2
# vxassist -g hrdg make hr_dv02 100M \
layout=mirror logtype=dcm mirror=2
2. Make the SRL on disks other than the ones used for the data volumes.
# vxassist -g hrdg make hr_srl 50m mirror=2
3. Make the RLINK.
# vxmake -g hrdg rlink hr_v240_rlk \
comment=”primary for HR at v240” remote_host=v240 \
remote_dg=hrdg remote_rlink=hr_v241_rlk \
local_host=v241 synchronous=off srlprot=dcm
4. Make the RVG, and associate the RLINK, data volumes, and SRL with it.
# vxmake -g hrdg rvg hr_rvg rlink=hr_v240_rlk \
datavol=hr_dv01,hr_dv02 srl=hr_srl primary=true
5. Attach the RLINK to the RVG.
# vxrlink -g hrdg att hr_v240_rlk
6. Start the RVG to enable I/O on the underlying data volumes.
# vxrvg -g hrdg start hr_rvg
